在发送到服务器之前进行图像裁剪/调整大小 [英] Image cropping/resizing before sending to a server

问题描述

我正在寻找一种解决方案，允许用户上传图像，裁剪图像，然后将更新的图像发送到服务器。

I am searching for a solution that will allow a user to upload an image, crop the image, and then send the updated image to the server.

基本上，我想处理所有编辑客户端，只将新的较小的缩略图发送到服务器。

Basically, I would like to handle all the editing client side and only send the new, smaller, thumbnail to the server.

我该怎么做？我已经看到这可以用Flash，但我正在寻找替代解决方案。

How can I do this? I have seen this is possible with Flash, but I am looking for alternative solutions.
